I'm a little confused about the difference between a "secondary name server" and a "slave name server" and a "primary name server" and a "master name server"
I understand that a slave name server queries the master and updates itself based on changes to the master. What I'm not sure of is, say I'm setting up 2 name servers:
Should both of these be setup as "primary and master" and then any secondary name servers be setup as slaves? Or should there only be ONE primary master at any given time, and all other name servers should be slaves?
I've read a few guides and lots of man pages, but I haven't come across this issue yet in my reading. Anyone have a pointer to a reference for this type of thing? Or know what the best practice is for setting up multiple DNS servers?
